I am also victim of these false cases filed by my brother's wife i am and NRI and still she filed the falses cases on me and my wife,I know the pain not making fun. if you can prove you have adultery proof's then you are safe.
my brother is also in the same boat as you, she was caught having affair with other person when everyone questioned her she ran to police station and filed false cases on us. and police are asking us to collect the proof's of adultery so i asked the same to you.
not making fun of you my friend.
